Description

Technical Field

[0001] This invention belongs to the field of postoperative incision protection technology, specifically relating to a surgical incision protection device for thoracic surgery patients. Background Technology

[0002] Following thoracic surgery (such as lung, esophageal, and mediastinal surgeries), the incisions are mostly located in the chest and abdomen, requiring a healing period of several months. During this time, the incision tissue is fragile and easily affected by the external environment and physical activity. However, current mainstream traditional dressing protection methods have significant drawbacks, specifically as follows: Traditional dressings lack tensile strength, making incisions vulnerable to damage. Traditional sterile gauze and medical tape only provide basic isolation and are completely incapable of resisting tensile forces. When patients move, the tension of the chest and abdominal muscles is directly transmitted to the incision, causing pain and delayed healing in mild cases, and potentially leading to incision dehiscence requiring secondary treatment in severe cases. This risk is particularly high for elderly patients or those with weakened healing abilities. Existing protective devices lack coordinated adjustment, resulting in insufficient tensile force protection. While some improved devices incorporate fixation structures, they are mostly independent static designs: either relying on rigid frames to restrict movement, leading to poor comfort and tissue compression; or using simple elastic bands for restraint, which cannot adjust the force according to the intensity of activity. When patients move or bend over, it is still difficult to accurately counteract instantaneous tensile forces, resulting in limited incision protection.

[0003] In summary, there is an urgent need for a thoracic surgical incision protection device that can accurately resist traction forces and adapt to dynamic protection requirements. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the prior art, the present invention provides a surgical incision protection device for thoracic surgery patients to solve the problems in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A surgical incision protection device for thoracic surgery patients includes a backplate assembly, on which a thoracic and abdominal assembly is provided. One end of the thoracic and abdominal assembly is connected to a strapping device. A lumbar support plate is provided on the lower side of the backplate assembly. A first fixing strap is provided on the lumbar support plate. An isolation protection device is provided on one end of the first fixing strap. A second fixing strap is provided on the lower side of the isolation protection device.

[0006] Furthermore, the chest and abdomen assembly includes a first shoulder strap connected to the back panel assembly, one end of the first shoulder strap being fixedly connected to the first chest and abdomen belt, and a second shoulder strap being provided on one side of the first shoulder strap, one end of the second shoulder strap being fixedly connected to the second chest and abdomen belt.

[0007] Furthermore, the back panel assembly is provided with a box, and a rear cover is provided on one side of the box. The box is provided with multiple strap devices, and the first fixing strap is provided with two straps. One end of the first fixing strap is fixed to the waist support plate by Velcro.

[0008] Furthermore, the isolation and protection device includes a protective housing connected to the first fixing belt, an observation window on the axis of the protective housing, a floating ring on the lower side of the observation window, a buffer airbag on the outer side of the floating ring, the outer side of the buffer airbag being connected to the inner side of the fixing ring, an elastic spoke on the upper side of the fixing ring, the lower side of the fixing ring being connected to the bonding base, a micro airbag inside the bonding base, and an annular adhesive on the lower side of the micro airbag.

[0009] Furthermore, multiple elastic spokes are evenly arranged, and the other end of the elastic spokes is fixedly connected to the floating ring. A transparent dome is provided on the upper side of the floating ring, and a buffer airbag is provided with a buffer airbag tube, and a micro airbag is provided with a micro airbag tube.

[0010] Furthermore, the bonding base is provided with an annular boss, a fixing ring is provided on the boss, one side of the buffer airbag is connected to the boss, the lower side of the bonding base is provided with a groove, a miniature pressure sensor is provided at the bottom of the groove, a miniature airbag is provided below the miniature pressure sensor, and an annular adhesive is provided in the groove.

[0011] Furthermore, the take-up device includes a mounting plate fixedly connected to the housing, a servo motor on one side of the mounting plate, the output end of the servo motor being connected to a rotating shaft, the rotating shaft being fixedly connected to a mounting cover plate, a shaft cylinder on one side of the mounting cover plate, a take-up drum on the outside of the shaft cylinder, a bushing at one end of the take-up drum, and an auxiliary roller on the outside of the take-up drum.

[0012] Furthermore, the strap-gathering device is provided in multiple parts, and the strap-gathering device is connected to the shoulder strap and chest / abdomen respectively.

[0013] Furthermore, multiple bushings are provided, and bushings are provided on the outer side of the mounting cover plate. The bushings are fixed on the mounting plate. The rotating shaft is connected to the winding drum via a spline, and the rotating shaft is connected to the mounting cover plate via a spline. The mounting cover plate is provided with a boss, and the outer side of the boss is connected to the winding drum.

[0014] Furthermore, tension sensors are provided on the first shoulder strap, the second shoulder strap, the first chest and abdomen belt, and the second chest and abdomen belt, and the tension sensors are connected to the controller.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This device works in conjunction with a strap retraction device and an isolation protection device. The strap retraction device can adjust the tension of the chest and abdomen components in real time based on a tension sensor. The buffer airbag and elastic spokes of the isolation protection device buffer the impact synchronously, forming a dual protection system of tension adjustment and buffer protection. This system can accurately counteract the traction force on the chest and abdomen generated when the patient moves or bends over, avoiding tearing or cracking of the incision due to traction and reducing the risk of secondary injury. The isolation and protection device achieves a close fit to the skin through micro-airbags and a ring-shaped adhesive backing, and uses a micro-pressure sensor to adjust the fit pressure in real time to avoid local pressure. The chest and abdomen component adopts a closed-loop structure that surrounds the shoulders and chest and abdomen, and is equipped with an independent tension adjustment function for the strap device, which can adapt to patients of different body types. In addition, the ergonomic design of the back panel component and the lumbar support plate can distribute local pressure. The Velcro connection between the first fixation strap and the lumbar support plate, and the snap-on assembly of the isolation protection device, allow the patient to operate independently without professional assistance when putting on and taking off the device. The observation window design of the protective shell allows for real-time monitoring of the incision healing status without disassembly, reducing the risk of infection caused by frequent disassembly and assembly. At the same time, all parts that come into contact with the skin are made of medical-grade materials. Attached Figure Description

A second shoulder strap 14 is provided on one side of the first shoulder strap 13, and one end of the second shoulder strap 14 is fixedly connected to a second chest and abdomen strap 15. Specifically, the first shoulder strap and the second shoulder strap are fixed to the first chest and abdomen strap and the second chest and abdomen strap, respectively, forming a closed-loop structure that encircles the shoulders and chest and abdomen. Its function is to stably wear the device on the patient's upper body, distribute the force on the chest and abdomen through the wrap-around design, avoid excessive tightness in certain areas that may compress the incision, and provide a basic carrier for the subsequent tension adjustment of the straps, ensuring that tension adjustment can be evenly applied to the chest and abdomen.

[0028] The back panel assembly 1 has a housing 11, and a rear cover 12 is provided on one side of the housing 11. Multiple strap-gathering devices 4 are located inside the housing 11. Two first fixing straps 5 are provided, with one end of each strap fixed to the waist support plate 3 via Velcro. Specifically, the housing provides installation space for the strap-gathering devices, and the rear cover facilitates component maintenance. The multiple strap-gathering device design meets the independent adjustment needs of different straps. The first fixing strap is fixed to the waist support plate via Velcro, allowing for quick assembly and disassembly and initial positioning of the isolation and protection device, improving the ease of use and adaptability of the device.

[0029] The isolation protection device 2 includes a protective housing 21 connected to the first fixing belt 5. An observation window 29 is provided on the axis of the protective housing 21. A floating ring 25 is provided on the lower side of the observation window 29. A buffer airbag 24 is provided on the outer side of the floating ring 25. The outer side of the buffer airbag 24 is connected to the inner side of the fixing ring 23. An elastic spoke 22 is provided on the upper side of the fixing ring 23. The lower side of the fixing ring 23 is connected to the bonding base 28. A micro airbag 27 is provided inside the bonding base 28.

[0030] Specifically, the protective shell 21 is made of medical-grade ABS material, the bonding base 28 is made of medical-grade silicone material, the annular adhesive 26 is made of medical-grade pressure-sensitive adhesive, and the airbags are all medical-grade silicone airbags. The protective shell provides external protection, and the observation window facilitates observation of the incision. The floating ring, buffer airbag, and fixed ring work together to buffer external impacts and tensile forces. The micro airbags and annular adhesive of the bonding base enable the device to fit tightly to the skin and avoid pressure. The overall structure forms a protective system of external protection, internal buffering, and tight fit for the incision. Its core function is to isolate the external environment, buffer tensile forces, and protect the incision.

[0031] Multiple elastic spokes 22 are evenly distributed, with the other end of each spoke fixedly connected to a floating ring 25. A transparent dome is provided on the upper side of the floating ring 25. A buffer airbag 24 is provided with a buffer airbag tube 241, and a micro airbag 27 is provided with a micro airbag tube 271. Specifically, the evenly distributed elastic spokes can help support the floating ring, enhancing its resistance to deformation, and further improving the buffering effect in conjunction with the buffer airbag; the transparent dome, together with the observation window, ensures the visibility of the cut; the buffer airbag tube and the micro airbag tube provide channels for the inflation and depressurization of the airbag, facilitating the adjustment of the buffering force and the contact pressure, ensuring that the device is adaptable to different usage conditions.

[0032] The bonding base 28 has an annular boss, on which a fixing ring 23 is mounted. One side of the buffer airbag 24 is connected to the boss. The lower side of the bonding base 28 has a groove, at the bottom of which a miniature pressure sensor is located. Below the miniature pressure sensor is a miniature airbag 27, and an annular adhesive backing 26 is located within the groove. Specifically, the annular boss provides a stable mounting point for the fixing ring and the buffer airbag, ensuring precise assembly of the buffer structure; the miniature pressure sensor in the groove can monitor the bonding pressure in real time, preventing excessive pressure from compressing the skin or insufficient pressure from causing poor adhesion; the miniature airbag and the annular adhesive backing respectively achieve pressure adjustment and sealing adhesion.

[0033] The take-up device 4 includes a mounting plate 47 fixedly connected to the housing 11. A servo motor 41 is provided on one side of the mounting plate 47, and the output end of the servo motor 41 is connected to a rotating shaft 42. The rotating shaft 42 is fixedly connected to a mounting cover plate 43. A shaft cylinder 44 is provided on one side of the mounting cover plate 43, and a take-up drum 45 is provided on the outside of the shaft cylinder 44. A bushing 46 is provided at one end of the take-up drum 45, and an auxiliary roller 48 is provided on the outside of the take-up drum 45. Specifically, the mounting plate provides a fixed foundation for each component, the servo motor serves as a power source, and drives the take-up drum to rotate through the rotating shaft to realize the take-up and unwinding of the shoulder strap or chest and abdomen belt; the bushing and the mounting cover plate ensure stable rotation of the rotating shaft, and the auxiliary roller guides the take-up and unwinding of the belt to avoid deviation; its core function is to precisely adjust the belt tension based on controller commands, providing power support to counteract the pulling force.

[0034] Multiple strap-gathering devices 4 are provided, each connected to the shoulder strap and chest / abdomen strap. Specifically, each strap-gathering device corresponds to a shoulder strap and a chest / abdomen strap, allowing for independent tension adjustment of each strap. This design aims to precisely adjust the tension of the corresponding strap to address the differences in traction forces generated at different locations when the patient moves or bends, avoiding uneven local stress caused by a single adjustment.

[0035] Multiple bushings 46 are provided, with bushings 46 located on the outer side of the mounting cover plate 43. The bushings 46 are fixed to the mounting plate 47. The rotating shaft 42 is connected to the take-up drum 45 via splines, and the rotating shaft 42 is also connected to the mounting cover plate 43 via splines. The mounting cover plate 43 has a boss, the outer side of which is connected to the take-up drum 45. Specifically, the multi-shoulder design improves the rotational stability of the rotating shaft; the spline connection ensures synchronous power transmission between the rotating shaft, the take-up drum, and the mounting cover plate, avoiding slippage that could affect the tension adjustment accuracy; the boss on the mounting cover plate cooperates with the take-up drum to achieve axial limiting, preventing the take-up drum from shifting.

[0036] Tension sensors are installed on the first shoulder strap 13, the second shoulder strap 14, the first chest and abdomen strap 16, and the second chest and abdomen strap 15, and these sensors are connected to a controller. Specifically, tension sensors are installed on the shoulder straps and chest and abdomen straps and connected to the controller, allowing for real-time collection of tension data from each strap. Their function is to provide real-time tension information to the controller, enabling it to accurately determine the magnitude of the pulling force and thus drive the take-up device to adjust the tension. Simultaneously, in conjunction with the isolation and protection device, a closed-loop control system of sensing, judgment, and adjustment is formed to ensure timely counteraction of the pulling force.

[0037] Working principle The patient places the device against their back, with the shoulder straps over both shoulders and the chest and abdomen straps wrapped around the chest and abdomen for initial fixation. The base 28 of the isolation and protection device 2 is aligned with the incision, the annular adhesive backing 26 is applied to the skin, and the first fixing strap 5 is tightened and fixed to complete the initial assembly.

[0038] When the patient moves, tension sensors on each strap monitor tension changes in real time. The controller, based on the sensor data, controls the corresponding servo motor 41 to operate, automatically adjusting the strap tension via the strap retraction device 4. Simultaneously, the isolation and protection device 2, through the synergistic action of the floating ring 25, the cushioning airbag 24, and the elastic spokes 22, dynamically absorbs and disperses stress at the incision site, forming an effective mechanical protective barrier. In particular, when the patient bends over or performs large movements, the strap retraction device and the isolation and protection device work together to ensure the stability of the device while avoiding excessive pulling force on the incision, effectively preventing wound dehiscence.
